Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
144 words
A diskette cartridge for a magnetic disk that is disposed for rotation within a housing, the diskette cartridge comprising: a recess near a peripheral edge of the housing having selected length and width dimensions and including an aperture for access thereto having an opening width dimension smaller than the recess width dimension; and a slide component having a width dimension smaller than the width dimension of the aperture, and having a length dimension larger than the width dimension of the aperture and substantially equal to the width dimension of the recess for admitting insertion of the slide component through the aperture in one orientation and rotation thereof within the recess to an orthogonal orientation with the length of the slide component traversing the width of the recess to support slideable movement of the slide component in said orthogonal orientation within the aperture and recess.
Claim 2
Dependent Claim
144 words
A diskette cartridge for a magnetic disk that is disposed for rotation within a housing, the diskette cartridge comprising: a recess near a peripheral edge of the housing having selected length and width dimensions and including an aperture for access thereto having an opening width dimension smaller than the recess width dimension; and a slide component having a width dimension smaller than the width dimension of the aperture, and having a length dimension larger than the width dimension of the aperture and substantially equal to the width dimension of the recess for admitting insertion of the slide component through the aperture in one orientation and rotation thereof within the recess to an orthogonal orientation with the length of the slide component traversing the width of the recess to support slideable movement of the slide component in said orthogonal orientation within the aperture and recess.
Claim 3
Dependent Claim
27 words
The diskette cartridge according to claim 1 wherein said slide component includes a substantially rectangular body having rounded corners to facilitate the rotation thereof within said recess.
Claim 4
Dependent Claim
18 words
The diskette cartridge according to claim 1 wherein said slide component is formed of a flexible, resilient material.
Claim 5
Dependent Claim
37 words
The diskette cartridge according to claim 1 wherein said slide component includes a body having dimensions smaller than the width of the aperture for protruding therethrough in said one and said orthogonal orientations of the slide component.
Claim 6
Dependent Claim
33 words
The diskette cartridge according to claim 4 wherein said body includes a slot depression in an upper surface thereof which protrudes through said aperture to provide rotational driving engagement with the slide component.
